Abstract (en)

[origin: WO0157160A1] Fischer-Tropsch synthesized hydrocarbons comprising both a 500-750 DEG F+ heavy fraction and a 500-750 DEG F -light fraction are separately hydroisomerized by a single-stage, two-zone hydroisomerization process, in which at least a portion of the light fraction is hydroisomerized in the first zone, with the total first zone effluent containing unreacted hydrogen and a light hydroisomerate. The first zone effluent and the heavy fraction are passed into the second zone to form a second zone effluent comprising the hydroisomerized product. The product is fractionated into a plurality of product fractions, including a distillate fuels fraction containing a jet fuel fraction. The hydrogen treat gas is used to separate a portion of the light fraction from the heavy fraction, prior to the hydroisomerization.
